我正在做我的应用程序，在我的手机上使用android 4.4.4工作正常但是当我在我的手机中运行android 2.3.7时出现错误。这是我的日志猫：

我正在使用Fragment，但支持库导入导入android.support.v4.app.Fragment。我片段的代码是：
import static com.nineoldandroids.view.ViewPropertyAnimator.animate;
import android.content.Intent;
import android.content.SharedPreferences;
import android.graphics.Typeface;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.preference.PreferenceManager;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.TextView;
public class Noticias_Fragment extends Fragment {
LinearLayout rl, container_leon;
View v;
int duration= 2000;
LinearLayout menu_capa;
Button button_;
Button button_4, button1;
LinearLayout container_2;
String sonido;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
v= inflater.inflate(R.layout.noticias_caratula, container, false);
SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(getActivity());
sonido= sharedPreferences.getString("sonido", null);
rl=(LinearLayout)v.findViewById(R.id.container);
container_2=(LinearLayout)v.findViewById(R.id.container_2);
container_leon=(LinearLayout)v.findViewById(R.id.container_leon);
menu_capa=(LinearLayout)v.findViewById(R.id.menu_capa);
button_ = (Button) v.findViewById(R.id.button2);
button1 = (Button) v.findViewById(R.id.button1);
button_.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
animate(menu_capa).alpha(0).setStartDelay(700).setDuration(900);
}
});
Typeface font = Typeface.createFromAsset(getActivity().getAssets(), "fonts/Roboto-Regular.ttf");
//Typeface fontdos = Typeface.createFromAsset(getActivity().getAssets(), "fonts/Roboto-Light.ttf");
TextView titulo_portada = (TextView) v.findViewById(R.id.titulo_portada);
titulo_portada.setTypeface(font);
button_4 = (Button) v.findViewById(R.id.button14);
button_4.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
animate(rl).alpha(0).setStartDelay(1600).setDuration(600);
new java.util.Timer().schedule(
new java.util.TimerTask() {
@Override
public void run() {
if(sonido.equalsIgnoreCase("si")){
MediaPlayer mediaPlayer = MediaPlayer.create(getActivity(), R.raw.rugido);
mediaPlayer.start();
}
}
},
1650
);
}
});
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
animate(container_leon).alpha(0).setStartDelay(2200).setDuration(600);
}
});
container_2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intenttresss = new Intent(getActivity(), FeedTabActivity.class);
startActivity(intenttresss);
}
});
button_.performClick();
button_4.performClick();
button1.performClick();
return v;
}
}
，错误行是：
View v= inflater.inflate(R.layout.noticias_caratula, container, false);
我的noticias.xml文件是这样的：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/marijai"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#333"
android:gravity="bottom"
android:orientation="vertical" >
<Button
android:id="@+id/button3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
<LinearLayout
android:id="@+id/container_2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/marijaidifumi"
android:gravity="center_vertical|center_horizontal"
android:orientation="vertical" >
<TextView
android:id="@+id/titulo_portada"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/circle"
android:text="Noticias"
android:textColor="#fff"
android:textSize="60sp" />
</LinearLayout>
<LinearLayout
android:id="@+id/container_leon"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/marijaidifumi"
android:orientation="vertical" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:visibility="gone" />
</LinearLayout>
<LinearLayout
android:id="@+id/container"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/marijai_sin"
android:gravity="bottom"
android:orientation="vertical" >
<Button
android:id="@+id/button14"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:visibility="gone" />
</LinearLayout>
<LinearLayout
android:id="@+id/menu_capa"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerVertical="true"
android:background="@drawable/marijai"
android:gravity="center_vertical|center_horizontal"
android:orientation="vertical" >
<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:visibility="gone" />
</LinearLayout>
</RelativeLayout>
并且错误的行是这样，但我看不出任何错误：
<LinearLayout
android:id="@+id/container"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/marijai_sin"
android:gravity="bottom"
android:orientation="vertical" >
有人能帮助我吗？感谢。
答案 0 :(得分：1)
片段在Android 3.0中引入。事实上，在Androids 3.0＆lt;支持 libary 使用Fragments的系统实现。有关更多信息，请查看http://developer.android.com/guide/components/fragments.html
请检查此链接Fragments in Android 2.2.1, 2.3, 2.0. Is this possible?＆amp; http://android-developers.blogspot.in/2011/02/android-30-fragments-api.html
